while in shallow water, the female lays in a push-up position while the male leans over to enter from behind. the male uses one hand to hold around the female's abdomen, keeping her's and his own lower body (primarily his erection and her vaginal or anal orifice) from submerging in the water. the male's other hand is used to hold the female's head in and pull it out of the water,at his discretion.
